Please help me in setting the baud rate in 89c51.I am doing project in 8051 which is a message transmitter.What i mean is there are two blocks in my project one is transmitter And other is receiver.
The transmitter consist of 64 keys which is obtained by 8*8 matrix key board.I am aiming for A to Z alphabets & 0 to 9 no.
After decoding which key is pressed i has to transmit the pressed key which will display on the receiver.I am planing to use 433Mhz transmitter & receiver the problem is that the transmitter and receiver has only 20kbps speed so i has to reduce the baud rate considerably.
If the 433MHz equipment is connected to the serial port, then any sample RS232 application should show you how to set the speed of the serial port.
Have you been looking?
this is the code i use for the serial
void Send_Character ( unsigned int Array [] ) $(SRC) { PUSH ACC ; store accumulater onto stack MOV P, ACC.3 ; get the bit for later PUSH B ; store the other data } theByte = Array[1]; ; get the data from calling code $(SRC) { MOV ACC, theByte ; get the only byte MOV SBUF2, theByte ; store it to uarter } Array = Array + 3; ; add to next bit for later $(SRC) { POP ACC ; get the accumulater back } return DONE_IT; }
How can i set the serial baud rate
which does not set the baudrate

Perhaps you'd like to actually answer the OP's question rather than just stating the obvious?
